Model system defined by zeros and poles of discrete transfer function
where Z represents the zeros vector, P the poles vector, and K the gain. The number of poles must be greater than or equal to the number of zeros (n ≥ m). If the poles and zeros are complex, they must be complex conjugate pairs.
The block displays the transfer function depending on how the parameters are specified. See Zero-Pole for more information.
The Discrete Zero-Pole block accepts and outputs real signals
more information, see Data Types Supported by Simulink in
the Simulink® documentation.
Specify the matrix of zeros. The default is
Specify the vector of poles. The default is
Specify the gain. The default is
Specify the time interval between samples. See Specifying Sample Time.
Use this parameter to assign a unique name to the block state.
The default is
' '. When this field is blank, no
name is assigned. When using this parameter, remember these considerations:
A valid identifier starts with an alphabetic or underscore character, followed by alphanumeric or underscore characters.
The state name applies only to the selected block.
This parameter enables State name must resolve to Simulink signal object when you click Apply.
For more information, see Discrete Block State Naming in Generated Code in the Simulink Coder™ documentation.
Select this check box to require that the state name resolve to a Simulink signal object. This check box is cleared by default.
State name enables this parameter.
Selecting this check box disables Code generation storage class.
Choose a custom storage class package by selecting a signal
object class that the target package defines. For example, to apply
custom storage classes from the built-in package
mpt.Signal. Unless you use an ERT-based
code generation target with Embedded Coder® software, custom storage
classes do not affect the generated code.
If the class that you want does not appear in the list, select
class lists. For instructions, see Apply Custom Storage Classes Directly to Signal Lines and Block
Select state storage class for code generation.
Auto is the appropriate storage class for
states that you do not need to interface to external code.
Applies the storage class or custom storage class that you select from the list. For information about storage classes, see Control Signals and States in Code by Applying Storage Classes. For information about custom storage classes, see Control Data Representation by Applying Custom Storage Classes.
Use Signal object class to select custom
storage classes from a package other than
State name enables this parameter.
Note: TypeQualifier will be removed in a future release. To apply storage type qualifiers to data, use custom storage classes and memory sections. Unless you use an ERT-based code generation target with Embedded Coder software, custom storage classes and memory sections do not affect the generated code.
Specify a storage type qualifier such as
Setting Code generation storage class to
SimulinkGlobal enables this parameter.
This parameter is hidden unless you previously set its value.
During simulation, the block uses the following values:
The initial value of the signal object to which the state name is resolved
Min and Max values of the signal object
